8B – 30 SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR)
DRIVER PRETENSIONER CIRCUIT, RESISTANCE TOO HIGH
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After passing these tests, the SDM will check the
driver pretensioner circuit. The SDM allows a very small
amount of current to flow through the circuit. The SDM
monitors the circuit resistance during this check.
DTC 09 Will Set When
D The combined resistance of the driver pretensioner
module, the harness wiring, and the connector con-
tacts is above a specified value, as in an open circuit.
DIAGNOSTIC TROUBLE CODE (DTC) 09
Open Circuit
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is discon-
nected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module. If the anti-deployment shorting bar on the
module-side of the connector is not working prop-
erly, the meter's battery can deploy the airbag and
cause injury.
